2?) all whom it may concern: The action of this device is as follows:

Be it known that I, WVILLIAM STANLEY, a When the device is disconnected from the citizen of the United States, residing at Great mains I I and the parts are at rest, the por- Barrington,Berkshire county,Massachusetts, tion A is out of alinement with the portionB 5 have invented certain new and useful Imand the cam G is out of engagement with the 55 provements in Indicating Systems and Timecontact F. If now the circuit from the mains Beaters, of which the followingisafull, clear, I I is completed, the coil E is energized, and exact description. which magnetizes the armature A, the circuit My invention relates to improvementsininbeing from the conductor I through the coil dicating systems and time-heaters forming a L, the coil E, the resistance R, to conductor I. 60 part hereof, and has for its object to attain This causes it to swing into line with the porsimplicity in construction and accuracy of option B.

The coil 1 is connected in series with to the cam G by the conductor 9. the coil E or so that it will be short-circuited R is a resistance in series with the wind whenever the coil E is short-circuited, the lugs E. cam G being connected to the circuit between 0 IIare mains ofa constantotential circuit. the coil L and the mainI b the conductor g. zoo 5 A P the coil E, so that the coil L receives an im-- pulse once during each oscillation of the armature A. The reciprocation of the coil L causes the indicator Q to move through the action of the pawl 0, thereby integrating the number of oscillations and indicating the time and constitutingatime-keeping system.

In the modification shown in Fig. 4 the short-circuiting device consists of a lever S, pivoted at s and connected to the conductor This lever is moved to and fro by the pin '1 on the shaft 0 and makes and breaks contact with the terminals U U, which are connected to the main 1. The breaking and making of engagement with the contacts U U energizes and deenergizes the exciting coil or windings, producing the results before described.

What I claim is 1. A time-beater consisting of the combination of a magnetic circuit having an oscillat: ing portion, a spring limiting the movement of said oscillating portion in both directions and tending to return it to a definite position, windings for magnetizing said portion connected to a source of current, a short circuit around said windings, and means for periodically making and breaking said short circuit and thereby energizing and denergizing said windings.

2. A time-beater consisting of the combination of a magnetic circuit having an oscillating portion normally out of alinement with the other part of said circuit, a spring limiting the movement of said oscillating portion in both directions and tending to return it to a definite position out of alinement with the other part of said circuit, windings for magnetizing said magnetic circuit connected to a source of current, ashort circuit around said windings, means forperiodically making and breaking said short circuit and thereby magnetizing and demagnetizing said magnetic circuit.
